The word "恋尸癖" is formed by sequentially combining the characters "恋" meaning love or attachment, "尸" meaning corpse, and "癖" meaning obsession or addiction; "恋" and "尸" together denote love directed at corpses, and "癖" is added to specify this as a pathological fixation, thus creating a compound term that literally translates to "corpse-love obsession" and denotes necrophilia.
